Kinetics of transfer of volatile amphiphiles (fragrances) from vapors to aqueous drops and vice versa: Interplay of diffusion and barrier mechanisms
Krassimir D. Danov, Theodor D. Gurkov, Rumyana D. Stanimirova +1
Subject of this work is to investigate the kinetics of mass transfer of volatile amphiphiles from their vapors to aqueous drops, and from the saturated aqueous drop solutions to ai…
Solubility of ionic surfactants below their Krafft point in mixed micellar solutions: Phase diagrams for methyl ester sulfonates and nonionic cosurfactants
Krassimir D. Danov, Rumyana D. Stanimirova, Peter A. Kralchevsky +6
Many ionic surfactants with wide applications in personal-care and house-hold detergency show limited water solubility at lower temperatures (Krafft point). This drawback can be ov…
Analytical modeling of micelle growth. 4. Molecular thermodynamics of wormlike micelles from ionic surfactants: theory vs. experiment
K. D. Danov, P. A. Kralchevsky, R. D. Stanimirova +3
Hypotheses: The aggregation number and length of spherocylindrical (rodlike, wormlike) micelles in solutions of an ionic surfactant and salt can be predicted knowing the molecular…
Encapsulation of fragrances and oils by core-shell structures from silica nanoparticles, surfactant and polymer: Effect of particle size
T. G. Slavova, G. M. Radulova, P. A. Kralchevsky +1
Oils and fragrances can be encapsulated by using composite shells of silica nanoparticles, polymer and surfactant (potassium oleate). The template for the creation of the core-shel…
Phase separation of saturated micellar network and its potential applications for nanoemulsification
M. T. Georgiev, L. A. Aleksova, P. A. Kralchevsky +1
Phase separation of saturated micellar network, as a result of cross-linking of branched micelles is established in mixed solutions of the anionic surfactant sodium laurylethersulf…
Analytical modeling of micelle growth. 3. Electrostatic free energy of ionic wormlike micelles -- effects of activity coefficients and spatially confined electric double layers
K. D. Danov, P. A. Kralchevsky, S. D. Stoyanov +2
Hypotheses: To correctly predict the aggregation number and size of wormlike micelles from ionic surfactants, the molecular-thermodynamic theory has to calculate the free energy pe…
Vortex in liquid films from concentrated surfactant solutions containing micelles and colloidal particles
E. S. Basheva, P. A. Kralchevsky, K. D. Danov +3
Hypothesis: New dynamic phenomena can be observed in evaporating free liquid films from colloidal solutions with bimodal particle size distribution. Such distributions are formed i…
Rheology of mixed solutions of sulfonated methyl esters and betaine in relation to the growth of giant micelles and shampoo applications
V. I. Yavrukova, G. M. Radulova, K. D. Danov +4
This is a review article on the rheological properties of mixed solutions of sulfonated methyl esters (SME) and cocamidopropyl betaine (CAPB), which are related to the synergistic…
Encapsulation of oils and fragrances by core-in-shell structures from silica particles, polymers and surfactants: The brick-and-mortar concept
Gergana M. Radulova, Tatiana G. Slavova, Peter A. Kralchevsky +3
Colloidosomes provide a possibility to encapsulate oily substances in water in the form of core-in-shell structures. In this study, we produced microcapsules with shell from colloi…
